To all whom it may concern.-

Be it known that I, FRANK A. YOUNG, a

' citizen of the United States, and a resident of so much ofguide-bracket being Syracuse, in the county of Onondaga and State of NewYork, have invented certain new and useful Improvements in Type-Writ yinvention relatesrlbbon vibrators, guides, main ob ect is tomoreespecially to or-carriers; and its readily may be easily and withdrawnor removed.

'T the above and other ends the invention resides in the features ofconstruction and combinations and arrangements of parts hereinafterfully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is an enlarged fragmentary perspective'view ofthe upper part of a type-writing machine and showing said machine'as isnecessary to clearlyillustrate my invention, art of the ribbon-guidebracket speedily hon-vibrator embodying my invention. Fi 3 is anenlarged front elevation of the ribboncarrier detached.

In the drawings, 1 represents the top plate of the machine, above whichis suitably mounted a platen 2. A vibrator guidebracket 3 is secured byheaded screws 4 to lugs 5, depending from the top plate, saidprovided'with two vert1callydisposed' parallel arms 6, the rear sideswhereof are formed with longitudinal grooves or 'guideways 7. Anink-ribbon 8 printing-point and is has its ends secured to a pair ofribbon-spools, (not shown,) one at each side of the machine above thetopplate and forward of the platen, and-said spools are designed to beturned by an y suitable ribbon-feeding mechanism in order to feed theribbon back and forth from spool to spool. The central portion of thatpart of the ribbon which extends across the machine between the spoolsin front of the platen is preferably normally maintained below theprinting-point and is during printing operation moved to cover thethereafter moved back to again uncover the printing-point. This to andfro or'vibratory movement of the rib-,

7 provide a ribbon carrier or vibratorin which the ribbon may be andexpeditiously threaded or engaged andfrom which it integral with saidslide. being bro en away. Fi'g. 2 is an enlarged side elevation of arib- 15, the front and rear faces of the finger 15 be-- are in the sametransverse save for the offset point or end of the guard bon iscontrolled by a vibrator, guide, or carrier, which is preferably made ofsheet metal and com rises a stem 9, a cross-head 10 at the top of thestem and consisting of arms extending laterally and upwardly from thestem, and a pair of slides 11, carried at the ends of the cross-head.The two side arms composing the cross-head are folded back on themselvesat 12, and the slides 11 are thereby turned toward each other and engagethe guideways 7 in the guide-bracket 3. The

. lower portions of the slides extend below and wardly and outwardlyextending guard-finger 14 and an upwardly and inwardly extendingguard-finger 15. The finger 14 is suported from the upper end of theslide 11 the bend or root a of the finger 14 being preferably Thedownwardlyexten'ding guard-finger 14 is preferably considerably longerthan the upwardly-extending finger and is through the greater part ofits length substantially parallel with the inner wall or edge of theguidin lower end the finger 14 flares or bends outwardly or sidewise, asindicated at 16, so that its lower end is slightly outside of or beyondthe end of the upwardly-extending finger 15, which latter throughout itslength is or may be parallel with'the inner edge of the slot 13.

he flare or offset 1 6, as best indicated in Fig. 2, is bent or directedrearwardly, so that the lower end of the finger 14 is also slight offsetand isbehind the upper end of the gei' upper part of the vibrator andthose of the ing inthe same planes. The arran ement is such that thereis a slight clearance 0th outwardly or laterally and tween the free endsof the guard-fingers 14 and 15. The Walls of each guiding-slot 13, itwillbe noted, are composed of members which plane throughout,

or finger 14, and this end 16 is offset outside or beyond theretaining-wall of the slot of which the finger 14 forms a part. It willfurther be observed that the combined lengths -slot 13. Near its fromfront to rear. be-

IOO

of each pair of associate guard-fingers exceed the length'of the slot 13of which theyform a part. 'lheguiding-slots 13 are shown diagonallyarranged, diverging from the top to the bottom, this construction beingpreferred, since it overcomes the objectionable slack at the lower edgeof the ribbon commonly found where vibrators having parallel slots areemployed. I do not desire, however, to be limited to the particulararrangement of the slots shown in the drawings. Any other angle ofinclination may be used or the slots may be parallel, if desired. Thelower end of v the stem portion 9 of the vibrator is provided with apivot-pin 17, which isengaged by the slotted forward'end of anoperating-lever 18,

which is actuated in a known marines-to cause the ribbon to cover anduncover the printing-point. Theufper ends of the slots 13 are closed bythe bend'sor roots at of the doWnWardly-projecting fingers 14, and hencethe ribbon cannot fly or jumpout of the vibrator during the operationvofthe printingkeys.

Referring more particularly to Fig. 3 of the drawings, the inner edge ofeach slot 13 is indicated by the reference-letter b; the opposing edgeson the fingers 14 and 15 by the let ters c and (1-, respectively; thelower orinner edge of the laterally-disposed free end of the finger 14by e; the outer edge of the upwardlyprojecting finger 15 by f; thepassage-way etween the fingers 14 and 15 by g, and the mouth of saidpassage-way by h. It will be noted that the edges f of the fingers .15are directed inwardly toward the center of the v1brator,so that in thepreliminaryo eration of threading the ribbon when the atter is bentaround the fingers 15 the ribbon is given wide mouth or entrance 7!.

a tapering shape by the inclined edgesf. The flaring end 16 of eachfinger 14 is so disposed with relat on to its associated finger 15 thatthe edges 0 and f of said fingers form a lateral passage-way g, which isobliquely disposed to the main slot 13 and has a comparatively When theribbon having been drawn taut against the fingers 15 is subsequentlymoved upward, it is directed toward the main slots 13, which it iscaused to enter by the overhanging fingers 14- by reason of the inclinedor flaring edges e of the latter, which tend to deflect or. guide the uper edge of the r bbon easily and smoothly through the passage-way g andthence into the slots 13. When the ribbon has once been brought into thecomparatively wide mouth h of the passage-way g and is moved upwardly,

it is inevitably guided into its Plot 13.

In order to thread the ribbon in the slots in the vibrator, said ribbonis passed down between the laten and the vibrator until the top edge oft e ribbon is below the free ends ribbon just beyond or outside of theo1 the'guard-fingers 14. The portions of the ardfingers are then bent orcurved forwar until they are beneath the ends of the fingers 14,considered from the front of the machine. The ribbon may then be movedupwardly and passed readily into the slot 13 between the ends ofthe'guard-fingers 14 and 15, and

after its upper edge has contacted with'the top of the slot the lowerportion of the ribbon may be drawn in and over the lower guardfingers 15until the ribbon is completely threaded or engaged in thevibrator-slots.

Preferably in inserting the ribbon it is drawn r taut against the outeredges of the lowersaid ribbon.- When completely threaded in v thevibrator, the ribbon, it will be noted, passes in front of theguard-fingers 14 and 15 and thence diagonally through the slots 13 andbehind the wings 11*. In order to withdraw the ribbon from the vibrator,itis only necessary to liftthe lower edge of said ribbon upward until itis just above the free ends of the fingers 15, whence .it may readily beslipped out of the slots through the openings between the ends of theguard-fingers The fingers or hook-like members 15 are comparativelyshort, so as to necessitate but slight buckling or creasing of theribbon When, it is threaded oru'nthreaded. The hooks 15, itwill beunderstood, serve as a support for the lower edge of the ribbon.

To engage or disengage the ribbon with the guide or vibrator hasheretofore usually been tedious and difficult and has necessltated aprotracted handling of the ribbon, thereby resulting in soiling thefingers of the operator to a considerable extent. employment of myresent invention, however', the operation 0 threading or 'unthreadingthe rib on in the vibrator may be readily By the and expeditiouslyaccomplished with slight handling of the ribbon.

I have illustrated my invention as applied to a front-striketype-writing machine resembling in its construction the Monarchtype-writer and have not, therefore, deemed it necessary to show anddescribe those parts of the machine which are not necessary to acomplete understanding of my invention.

It will be understood, however, that the invention may be embodied inother forms of writing-machines employing a ribbon-guide of the classdescribed or of any other description, for it willbe understood that inso far as the main features of my invention are concerned it isimmaterial whether the ribbonguiding device vibrates or reciprocates orwhether it .-be normally fixed against such movement, although I preferto employ my novel ribbon-guide in a machine wherein it is reciprocatedto cover and uncover the printing-point during the operations of thekeys and leave the last letter exposed when the parts are in normalposition. It is further to be understood that various constructionalchanges may be efiected within the scope of my invention.
